Have a Project for 30 Volunteers on June 29?

A local group contacted Habitat about having ~90 volunteers serve with us on June 29. While I truly appreciate their belief in our capabilities :-), we cannot host that many volunteers on a single job site.

Might you have a large project that 30 strong, capable volunteers could complete in 4 hours on June 29? The volunteers will be in the 15 – 19 age range and will be accompanied by older adults.
